The Packing Cube Shoulder Bag is a dual-purpose packing cube: in
preparation for and during your journey, use it to organize and pack
your clothing inside the Aeronaut, Tri-Star, or Western Flyer — just
like how you'd use our Packing Cubes. When you reach your destination
and it's time to leave the Aeronaut, Tri-Star, or Western Flyer in the
hotel or hostel, repack the Packing Cube Shoulder Bag with a light
jacket, wallet, lunch or small water bottle, map, and add a shoulder
strap: you're ready to go out and explore, and you've saved space by not
having to bring a separate bag for day use.

Made out of our 200 denier Japanese Dyneema®/nylon ripstop fabric, the
Packing Cube Shoulder Bag is very lightweight yet durable enough for a
lifetime of use for most folks.

The Packing Cube Shoulder Bag has two pockets/compartments, both of which
zip with a #5 YKK coil zipper. We specifically chose
plastic sliders for this zipper because they won't corrode or set off metal detectors.

We don't include a shoulder strap with the Packing Cube Shoulder Bag because
you can simply transfer the Absolute Shoulder Strap from your
Aeronaut, Tri-Star, or Western Flyer to the Packing Cube Shoulder Bag.
If you'd like a second shoulder strap for the Packing Cube Shoulder Bag,
or simply a lighter shoulder strap, choose the optional Simple
Shoulder Strap.
